WH EELED ROAD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 350,136, dated October 5, 1885.

Application tiled ltl'urch 5, 1886.

To all 2071 om it may concern.-

Be it known that I, \VILLLUI l Jncons,a citizen of the United States, residing at (Jolumbus, in the county of Franklin and State of Ohio, have invented certain new and useful improvements in \Vheoled Road Scrapers; and I do hereby declare the following to be a. full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to road-scrapers mounted on wheels; and it consists of certain novel constructions of parts as will be hereinafter fully described and specifically claimed, where.- by the manipulation of the scraper is' greatly facilitated, aswill be seen.

In the accompanying drawings, Figure 1 is a side elevation of my scraper as it appears when loaded and being moved to the place for dumping. Fig. 2 is a. side elevation of the same as it appears after being dumped and while being inoved back 'for another load or being transported. In Figs. 1 and 2 the wheel in front of the observerisremoved in order to better expose the mechanism concealed by it. Fig. 3 is a side elevation of my scraper in the art of scraping, showing a checking mechanism of the bowl by breaking away such parts as were in front of it. Fig. 4 is a view of Fig. 1, partly in plan and in section.

The letter Ain the drawings representsthe bowl, 1 an axle, 0 wheels, and D a tongue, of a mad-scraper. lhe bowl A is suspended by means of rigidly-attached hangers a to the inneror cranked portion, 1), of the axle B, around which portion it is swung into the required positions by means of handles a and leversand other parts, as will now be described.

A lever-frame, E, 0i forked shape, is pivoted by means of its two arms, 0, to the bowl A at The arms 0 extend a suitable distance beyond the pivots a", and near their terminations are provided witlra draft-bail, F,

draft-rod, f, is connected with the bail F for the purpose of attaching what is .called a snatch-team. This draft-rod is suspended in a suitable ring-pin, f, by the tongue D. The rcarportion of this tongue is provided with braces d d, which extend rearward along Serial No. 194,152. (No model.)

of the bowl and standing very near to the axlespindles b b, and nearly on the same horizontal plane of said spindles when the bowl is lit the raised horizontal position shown in Fig.1,

serve a very important purpose-viz., by being thus located the tongue can be set high amteonnected far back out-he bowl, and thus in dumping the load it is easy to turn up the bowl when the edge thereof engages with the earth. Near the pivots ahthe braces dare provided with pins or 'lugsd d", and hear these pins the arms cc of the lover-frame are provided with lugs e e, which engage with the said pins when the bowl. is used for scraping, the pins d d and lugs e c preventing the bowl from turning over while it is being filled by locking the bowl tothe tongue-braces d d, this being effected by the lugs e 0' on leverl'ramc E standing over and engaging with the pins d' d on tongue braces when the bowl is down and lever-frame up, as shown in Fig. 3 of the drawings. The pivots d d servo also to support two arms, g g, of an endgate, G, by which the open front of the bowl A is closed, while the bowl is being transported .in its elevatislposit-iou, as shown in Fig. 1. The arms 1 g are provided with gutter-shapedlugs g g, which extend horizontally over the braces dd and lugs c e, and have. vertical laps g The arms 0, near the wheel-axles I) b, are provided with links whereby they are connected with said axles. The end portions of the pivots a a and d d are. steadied by ordinary brackets, J which are suitably fastened to the sides of the bowl A. The central part or handle, e",of the lever-frame E is provided with a double pawl, K,- having a fulcrum, k,handle is, upper hook, k", and lower hook, If. The lower hook, If, engages with a suitable lug, a, on the rear side of the bowl A, andthus prevents the bowl from tilting backward. The upper hook, it", engages with a fixed hook, Z, on a suitable standard, L, of the tongue I), when the levert'rame E is turned up into a vertical posit-ion, as seen in Fig. 2. In this position the leverframe holds the bowl A by means of the said hook It", away fronrthc groi'ind, asscen in Fig. 2, and the hook k" may be enu iloyed as a further means-for holding the bowl in said vertical position, and thus adjusted the road scraper is moved from place to place by an ordinary team: attached to thepin D When the'bowl is to be used for scraping, the lever-frame E is disengaged from the stand-'- ard L by unlocking the upper hook, It, from the hook I, and said frame isturned down with the bowl, and the bowl is turned up until the pins (2" touch the lower surfaces of the lugs e,

whereby the bowl is lowered suflicienlly to enfer-the ground a suitable depth, as illustrated in Fig. 3. At this stage a snatch-team is attached in a suitable manner to the front end of the draft-rod f in'order to apply additional draft-power to the road-scraper. When the bowl has entered the ground, the operator controls and guides it-.by pressing down the bowl with one hand on a handle, a, and holdsup theleVer-frame E with his other hand, thereby causing the pins 66 d to be held in firm con.- ne'ction with the lugs e e, as shown in said Fig. 3, andthe bowl A to remain in a steady position. While the parts were being adjustedlto the position described and. shown, the laps gig of the'lugs-g g were caused to come fromtheir.normal inicontact with the lugs e e and be elevated v position shown in Fig 1 and theend-g'ate G to be thrown up so as to permit the scrapedor loosened earth to freely enter. the bowl A. Then the bowlA is filled the lever-frame E is. turned down, swinging on the links I. and by means. of pivots 'a a lifting. the bowl A from the ground, and causing. the hangers. a a and bow-l to be lifted by moving thewheel-axles b b toward saidhang' ers, thereby elevating the cranked portion bof the axle B-to which said hangers areattached.

By this elevation of the bowl A -the gate-arms g and tongue-braces d assume a parallel. posi-' tion, vpermitting the lugs g to descend and. the end-gateG by its weight to also descend and close up the bowl A. The snatch-team is now unhitched' from the road-scraper. andonly the permanentteam used for movi ngthe filled. bowl to the place of dumping its load. On arrival at the placeofdumping the operator raises the lever-framewith the bowl locked thereto until the. cuttingwedge a of the bowl takes. a

holdin the ground, whereu'pomthe ground serving as a fulcrum for. the bowl and. lei/gerframe, they are pulled over by the draft of I theteam. Assoonasthelever-frameEis raised for the purpose of dnmping,.thelugs' g of the end-gate-JG are moved up. by the bralcwv d of the tongue D,.and they holdup said end-ga e, so as to permit. the contents ofthe bowl to freely and entirely pass out from the bowl.

The operator'now turns the lever-frame, with the bowl, farther forward or. toward the stand.

ardL' until .the hookslandk become interlocked and the roadrscraper isadjusted, as

- shown in Fig.2, for. return tojthe place of scraping, and. repeating the above-described operation.

It. is not essential. that the latch k be engaged with the Inga? of the. bowl when in the position shown in Fig. 2, as. the bowlcannot turn back. under ordinary circumstances, so

long as the catch is engagedwith the 11001;

I of thestandard L.

The end-gate can be easily removed, if desired, and again asreadily attached, it espe; cially being "useful when the machine is employed in digging sandy or dry'soil liable to run or spill out.

The wheel-axles b, as shown in Fig. 4, are

provided with sleeves M and flanges m,shrunk upon them, the flanges m being let into the wheel-hubsc. These sleeves can be more readily constructed separately from and shrunk upon the crank-axle than wrought upon said anfle, and they are important for the purpose above stated, while they serve as wearingwashers for keeping the links I of the scraper mechanism from rubbing on or against the wheel-hubs, in order to prevent sand and mud from entering between the bearings of the wheels and sleeves, which are lined or bossed is. usually in practical. machines. a slight degree of playallowedv between the pins d and logs e, in order that. the. operator may adj nst the bowl to the most. suitable inclination for efl'eetually cutting the. ground and. filling the bowl. It will also be seen that inproviding for hitching the snatehrteani to the front ends of thelever-frame E and beyond its pivots a the labor of the. operatoris lessened in the filling of thebowl' and the lifting of the same, because the draft. of the team: works in an upward di- \Vhenthe rection upon the pivotsw, and atfords leverage helomthe pivots. for. lifting. the bowl, which leverage is acted upon by the draft of the snatchteam. By pivoting. the tongue separately to the bowl and near the. top thereof, the dumping of the. bowl-is facilitated, because A j while the operator raises the handles-a the 1 nearly in a horizontal-line, and thus the draft of the team causes only a very slight resist ance to thejraising of said handles until the front of the bowl is engaged with the ground as. a fulcrum, when the. new leyeragethus gained 'enablesthe team to pull the bowl over as far as needed. Another-advantage over pivots d of the bowllaudthe wheel-axles stand other known constructions results from the employment of the lugs e. e and pins d d, whereby the position of the bowl is rendered steady while scraping or gathering a load, and, furthermore, the end-gate being automatic in its operation adjustsitselt to the angle of the Thus when the bowl is entered into the-ground the end-gate rises and leavesan opening for the entrance. of the earth. into. the bowl, and-when the bowl is horizontal this end-gate. forms a closing end piece, and during the dumping operation it will stand wide open. With thc do'uble pawl K and lever-frame E the bowl can be steadied in its two main positions, as described, thereby rendering the management of the bowl comparatively easy to the operator.

What I claim is- 1. In a wheeled road-scraper, the combination of the crank-axle B, hangers a, pivoted links I, suspended bowl A, lever-frame E, and tongue D, the pivotal connections of the lever frame and tongue being near the top of the bowl and nearly on the same horizontal plane, substantially as and for the purpose described.

2. In a wheel-scraper, the combination of the crank-axle B, hangers a, pivoted links I, lever-frame E, a suspended bowl, A, having pivots (2, located near the top edge of the bowl, and a tongue, D, pivoted at d to the bowl, substantially as and for the purpose described.

3. In a'wheeled road-scraper, the combination of a-crankcd axle, B, a suspended bowl, A, a lever-frame, E, pivoted to the bowl A at a, and a draft-bail, F, for a snatch-team at.- lached to lever-extensions of the lever-frame beyond the pivots a, substantially as and for the purpose described.

4. The combination of the bowl A, having pivots d a with the tongue-braces d, having pins 41, and the lever-frame E, having lugs e,

I substantially as and for the purpose described.

5. The automatic end-gate G, having lugs g, in combination with the bowl having pivots d, and; with the lever-frame E, having lugs e, substantially as described.

6. The combination of the swinging bowl A, having lug a, the lever-frame E, having; double pawl K, link I, axle B, and the tongue-standard L, having hook Z, substantially as and for the purpose described.

7 The combination of the cranked axle I tongue-standard L, having hook I, the swinging bowl A, and lever-frame E, having book If, substantially as described.

8. The cranked axle B of a wheeled roadscraper, having sleeves M, with flanges m secured removably upon its spindle-arms, in combination with the links I, and wheels C, having hubs with connterborcs around their eyes at their inner ends for the close seating of the flanges m, substantially as and for the purpose described.

In testimony whereof I afl'ix my signature in presence of two witnesses.
